Abstract: A method and system are provided for positioning characters within an arbitrarily sized graphics window in order to maximize the distribution of unused space. The method and system are particularly adapted for the redistribution of characters produced during a terminal emulation session with another computing system. Characters produced during the emulated session are adjusted to completely fill the graphics window, regardless of its size. A till justification procedure distributes characters in areas within the graphics window that would otherwise appear as gutters or margins. A character spacing unit maintains correct character image proportions in the graphics window while not rigidly adhering to a uniform alignment of character rows and columns. A linear distribution procedure allows the character image to fill the graphics window completely with a natural appearance.

Title: Method and device for switching, amplification, controlling and modulation of optical radiation
Inventor: MAIER ALEXANDR ALEXANDROVICH
IPC: G02F1/017
Filed: 1998-06-11
Abstract: The invention has improved parameters when compared with prior art devices;  pump power was decreased by four orders and amplification of signal was increased by two orders. The main features of the invention are following. The nonlinear optical waveguide (1) is made on the basis of layered MQW-type structure, where unidirectional distributively coupled waves (Ip, Is), e.g.  coupled waves having orthogonal polarizations, interact. Wavelength of optical radiation is chosen close to wavelength of resonnance in said structure.  Input/output elements (10, 11, 12), taking into account the asymmetry of cross section of the nonlinear optical waveguide, are mounted at the input and output of the nonlinear waveguide making up a compact nonlinear-optic module.  A small electrical current is injected across said nonlinear optical waveguide through the electrodes (2, 3), so as to increase gain and decrease pump optical power in high degree. The device contains also Peltier element and temperature sensor which help to obtain low predetermined critical power of pump radiation necessary for large signal gain and to set up necessary operation mode. The method of mounting and construction of optical elements of the device is also claimed. The technological reserves can improve already achieved record parameters. Application as all-optical transistor, all-optical switch, logic element and devices based thereon.

Patent CA-2306114-A1 (CA)
Inventor: ESTER GARY W
IPC: H04B10/038
Filed: 2000-04-14
Abstract: The system and method for eliminating the capacity required for protection of a line system includes a first tributary located on a first side of an optical line system. The first tributary carries an electrical signal into a first working multiplexes. The first tributary also has a first tributary switch which may be used to redirect the electrical signal around the first working multiplexes. If the first working multiplexes is functioning properly, the first working multiplexes multiplexes the electrical signal to the appropriate line rate and the signal is transmitted through the first working multiplexes to a first optical switch located on a first optical fiber, and then into an optical network. The optical network is located between the first and a second side of the optical line system.      If the first working multiplexes fails, a microprocessor detects the failure, activates the first tributary switch and the first optical switch, and coordinates the rerouting of the signal from the first tributary through a first protection multiplexes. The first protection multiplexes multiplexes the signal to the required line rate and the signal is transmitted to the first optical switch located on the first optical fiber. The signal is then transmitted into the optical network. Once the signal passes through the optical network, the signal is transmitted to a second working multiplexer on a second optical fiber. Finally, the signal is transmitted onto a second tributary. The system and method of the present invention is expandable to provide protection to any number of working channels using the protection multiplexer.

Patent CA-2307304-A1 (CA)
Title: Arrangement for obtaining reliable anchoring of a threaded implant in bone
Inventor: FROMELL ROGER
IPC: A61L27/00
Filed: 1998-11-03
Abstract: In an arrangement for obtaining reliable anchoring of a threaded implant (3) in dentine, a hole (2) is made in the bone substance. In the side wall (2b) of the hole it is possible to establish an internal threading which can cooperate with an external threading (3d) on the implant. The implant threading is arranged to force the bone substance out in essentially radial directions as a function of the extent to which the implant is screwed into the hole. The threading is arranged to effect greater forcing out of the bone substance at the outer parts of the hole than at the inner parts of the hole. The degree of forcing out is adapted in relation to the softness of the bone in order to achieve the reliable anchoring. Along at least part of the longitudinal direction of the implant, the implant threading can be given a non-circular configuration for the purpose of obtaining improved rotational stability in soft/weak bone. The implant can also have two or more thread spirals/thread entries which shorten the time for screwing the implant into the hole and additionally offer tight threading which permits effective integration with the bone substance during the healing-in process.

Patent CA-2310956-A1 (CA)
Inventor: NALWA VISHVJIT SINGH
IPC: G03B37/00
Filed: 1999-07-08
Abstract: A compact high resolution omnidirectional or panoramic viewer has several cameras with a common virtual optical center. The field of view of each of the cameras is arranged to form a continuous 360 degree view of an area when taken as a whole. The cameras are positioned so that they each view a different reflective surface of a polyhedron such as a pyramid. This results in each camera having a virtual optical center positioned within the pyramid. The cameras may be positioned so that their virtual optical centers are offset from each other. The offsets produce narrow blind regions that remove image distortions received from the edges of the pyramid's reflective surfaces. The reflective pyramids may be stacked base to base or nested within each other to produce a more compact panoramic viewer. Using two or more reflective pyramids in such close proximity permits using many cameras with the same virtual optical center. Using many cameras divides a large viewing area into many smaller areas where an individual camera views each smaller area. Since each camera views a smaller area, increased resolution is provided to the user. The pyramids are mounted to a post that passes through their vertices, and the cameras are secured to the portion of the post extending out of the vertices.
